[Qt-interest] QT power switch

Mon Nov 23 18:09:01 CET 2009

Well, the html posted it's the welcome page. When you get in, you can see
the options to turn off and on the outlets. But when you make some clicks to
do that, on address bar i see -> http://mypowerswitch/outlet?1=ON. So i
thought i could go forward to this action loging me first.

By other way, i was trying to make an analog code from this perl code that
works fine for this objective.

use LWP::UserAgent;
$ua = LWP::UserAgent->new();
$ua->get('http://user:xxxx@mypowerswitch/outlet?1=ON);
